Hi, thanks for reading. I want to know some advice about this trouble. I jumped from an Phenom 955 with a 780G+SB710 board to a shiny 3570K paired with H77 chipset, both ASUS boards (M3A78-EM, P8H77-M PRO, yeah love the MicroATX). The reason for the move wasnt the performance upgrade, actually was the **** AHCI support on the SB710 that gave me just headaches with the SSDs i have tried (GSkill Evo 115GB and Vertex 3 120 GB). Since then the SSD works like a charm but with Intel RST the hard drive performance under AHCI loads (concurrent loads) its AWFUL. Just feels like the RST is tring to push to much data from the first thread (like in IDE mode) rather than ordering the requests to attend everything as fast as possible, and this actually never happened with the AMD platform, the hard drive in AHCI worked just fine.

Yes i have installed both latest BIOS and RST. The Vertex3 is hook up to a 6 Gb SATA. The trouble isnt with the SSD but with the HDD. For example: if i start a copy from or to the HDD and try to navigate its content through explorer while its copying, each access to a dir in the HDD takes a few seconds (with the Phenom it was instant always).

I have installed Intel RST only because i thought it could bring me the maximum performance from the system, but if it keeps troubly ill go back to MS AHCI generic drivers.
